Hardware Trojans: The defense and attack of integrated circuits

Abstract

Despite the increasing threat of hardware Trojans in modern circuits, there is currently a lack of Trojans available with which to test anti-Trojan techniques. This paper presents both a defensive technique designed to aid in the detection of Trojans in integrated circuits, as well as a design ideology to confound similar defensive techniques. The defense structure was awarded 2nd place in the 2009 Embedded Systems Challenge (ESC) competition, and Trojans following the attack ideology were submitted to the same competition the following year.
